A transponder can be CONUS (continental united states) or Spotbeam. A Satellite usually has 26 CONUS transponder's, by using Spotbeam's they can have 60 or more transponder's by re-using TP frequency's in that band.
Reason I ask is I was messing around with the point dish feature. Had it on the 110 SAT and was toggling the transponders and some of them changed to spotbeams after locking.
That's Dish terminology - should be type of transponder: 'conus' and 'spot beam'; a transponder still doing same functions, but a shape of antenna is different.
